Abstract

The invention relates to a private data pricing method, device and equipment and a readable storage medium, and relates to the technical field of data transaction. Comprising the following steps: screening out a first original data set from an original database according to a data object analysis function published by a buyer, and processing the first original data set based on a noise scale corresponding to acceptable data precision to obtain a privacy data set; respectively calculating information entropy and precision loss based on the data content and the root mean square error of the privacy data set, and calculating data value according to the information entropy and the precision loss; calculating the privacy content according to the attribute limit value of the privacy data set, the sensitivity of the data object analysis function and the acceptable data precision, and calculating the privacy cost based on the privacy content; calculating a data profit based on the data value, the privacy cost, and the data marketplace coefficient; and determining the price of the privacy data set according to the data value, the privacy cost and the data profit. According to the method and the device, accurate pricing of the data set can be realized, and customization requirements of users for different precisions are met.

Description

technical field [0001] The present application relates to the technical field of data transactions, and in particular, to a privacy data pricing method, apparatus, device, and readable storage medium. Background technique [0002] With the development of the Internet and the continuous maturity of digital technology, the applications and services of big data continue to deepen and expand in scale. By digging into cross-domain data resources and discovering the economic laws behind the data, it can effectively promote the transformation of all walks of life Upgrade and leapfrog development. However, the current data sharing and circulation rules cannot meet the strong demand for data resources of various applications, forming a large number of data islands. Therefore, it is urgent to establish a big data sharing and trading platform to realize a reliable data pricing mechanism, promote data circulation, tap data value, and release data potential. [0003] In this context, d...
